Understanding Cause, Motion, and Forces

What is the relationship between cause and effect in scientific terms?

• Cause always follows effect

• Effect is independent of cause

• Cause leads to effect

• Cause and effect are unrelated

How can you classify motion in terms of force?

• Motion is independent of force

• Motion is a result of force

• Force stops motion

• Motion and force are unrelated

What is an example of a real-life application of Newton's first law?

• A car accelerating

• A ball rolling on a flat surface

• A rocket launching

• A bird flying

What happens to an object when balanced forces act on it?

• It accelerates

• It changes direction

• It remains in its current state

• It stops moving

What is a practical example of balanced forces?

• A car accelerating

• A book resting on a table

• A plane taking off

• A ball being thrown

Which of the following best describes speed?

• Distance traveled per second in a specific direction

• Distance traveled per second

• Time taken to travel a distance

• Change in velocity over time

A car travels 20 meters in 1 second. What is its speed?

• 20 m/s

• 20 m/s to the right

• 1 m/s

• 1 m/s to the right

If a car's speed is 20 m/s, what additional information is needed to determine its velocity?

• Time

• Distance

• Direction

• Acceleration

How is velocity different from speed?

• Velocity includes direction, speed does not.

• Speed includes direction, velocity does not.

• Both are the same.

• Velocity is the rate of change of distance.

Which statement is true about magnetic force?

• It is caused by the size of the magnet

• It is caused by the motion of charges

• It is caused by the color of the magnet

• It is caused by the temperature of the magnet
